Saia v. New York

Saia v. New York, 334 U.S. 558 (1948), was a case in which the Supreme Court of the United States held that an ordinance which prohibited the use of sound amplification devices except with permission of the Chief of Police was unconstitutional on its face because it established a previous restraint on the right of free speech in violation of the First Amendment. — Excerpted from Saia v.
